Hello,

I would like to calculate the average of a certain parameter in a specific cellZone/region of the mesh. Using parameter.weightedAverage(mesh.V()).value() returns the average for the entire mesh, I would like to calculate it for a specified region or cellZone. I think it should be quite easy, but I don't get it to work...

thanks,
Guido

Hi,everyone

I have a similar problem: How to create an average over some region of space(an CV and its neighborhood)e.g. for smoothing or for numerical stability?

Hello,

I've got the same problem: How can I calculate weighted average of variables p & T in a given cellSet (with or without ParaView)??? Help really needed!!

Thanks

Bernhard Gschaider wrote a handy routine that calculates mass flows through a given faceSet:

Perhaps you could adapt the methodology to operate on cellSets?

Dear all,

@sub-averages: Mike is right and there are also a few function objects in the vanilla 1.6 which do something similar. However, all of this needs coding.

@smoothing by averaging: You can use the cellCells addressing, but this will not paralelise easily. Better solve a relaxation equation (laplacian).

Hi,

thanks for your replys! But the mentioned things seem to write out during run. My run needs 2 weeks so I'd like to post process the already written results... Is that possible?

calcMassFlow is a stand-alone utility that operates on your saved time directories.
